National Fuel connects you with leading manufacturers and stays current on the latest innovations from research organizations like the Gas Technology Institute to help you navigate today’s commercial gas equipment options.

From advanced water heating systems to precision humidity control, we can help you identify the right technologies from qualified manufacturers — solutions that can reduce your energy overhead, improve indoor air quality and deliver measurable returns on your investment.

Explore the equipment options below to find solutions that match your facility’s specific needs.

When you convert from electric to natural gas for water heating, you typically see monthly energy cost reductions while gaining access to more reliable, precise performance. Direct-vent water heaters represent one of the most efficient technologies available for commercial applications.

Efficiency, performance and simple installation

Direct-vent water heaters use sealed combustion systems to deliver hot water with exceptional efficiency. Unlike traditional water heaters that draw air from inside your building, direct-vent models pull fresh outdoor air through one pipe and exhaust combustion gases through another.

Benefits of direct vent water heating include:

• A closed-loop design that protects indoor air quality and can help eliminate back-drafting concerns.
• Installation flexibility with multiple venting configurations that work in tight commercial spaces or retrofit situations.
• Advanced electronic controls that provide precise temperature management.

The combination of high efficiency, flexible installation, precision controls and lower natural gas fuel costs adds up to substantial savings month after month. Whether you’re replacing aging electric water heaters or upgrading from older gas models, direct-vent technology offers a clear path to better performance and lower costs.

As buildings have become more energy efficient with tighter seals and better insulation, they often trap moisture inside. Natural gas humidity control systems help you manage these challenges effectively while reducing energy consumption compared to electric alternatives.

Protecting your infrastructure with humidification and dehumidification

Effective humidity control delivers measurable benefits. The right humidity levels make indoor spaces more comfortable year-round, reduce airborne irritants and respiratory discomfort, extend HVAC equipment life by reducing strain on your system, and protect wood floors, furniture and building materials from moisture damage.

Humidity control options include:

• Natural gas humidifiers add moisture and work seamlessly with existing HVAC equipment to maintain comfortable humidity levels.
• Desiccant dehumidification systems remove excess moisture using specialized materials that absorb humidity from the air and work best in spaces with high moisture loads or where you need precise humidity control.

Take control of your energy needs with natural gas on-site power generation. These systems provide a practical alternative that helps you manage costs while maintaining reliable electricity for your operations.

Natural gas technologies give you flexibility in how you generate and use power. Whether you need backup electricity during emergencies or want to reduce demand charges during peak hours, on-site generation puts you in the driver’s seat. These systems can power your entire facility or just the critical areas that keep your business running.

• Microturbines provide distributed power generation with low emissions and high reliability. These compact systems can help reduce your electricity costs while providing backup power capabilities.
• Fuel cells convert natural gas into electricity through an electrochemical process, delivering efficient, clean power with minimal environmental impact. They’re particularly valuable for facilities that need reliable, continuous power.
• Combined heat and power (CHP) systems capture heat that’s normally wasted during electricity generation. CHP works well for large facilities with consistent heating and cooling needs, such as hospitals, manufacturing plants and university campuses.
• Distributed generation lets you produce electricity right where you need it. Instead of relying entirely on the power grid, you can generate some or all of your facility’s electricity on-site.
• Peak shaving systems help reduce electricity costs by generating power when utility rates are highest. When demand charges spike, your on-site system can take over, helping lower your monthly energy bills.

Our collaboration with equipment manufacturers and research organizations extends across the full spectrum of natural gas technologies including foodservice equipment.

Commercial foodservice equipment running on natural gas delivers faster heating, precise temperature control and lower operating costs compared to electric alternatives. From ranges and ovens to steamers and fryers, natural gas equipment helps foodservice operations run more efficiently.

A wide variety of building types including schools, multifamily residences, medical facilities and office buildings can see significant improvements with properly specified natural gas equipment.

Facility managers appreciate the lower operating costs, improved performance and reduced maintenance requirements compared to electric alternatives. If you’re experiencing moisture problems, uneven comfort conditions, high energy bills or frequent equipment maintenance, natural gas solutions can help address these operational challenges.

We understand that equipment decisions impact your bottom line. The right natural gas solutions can help you control costs, improve operational efficiency and create better environments for the people who use your facilities. You may even be able to benefit from incentives and rebates when you take advantage of new natural gas equipment.
